• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"national regional state\") OR (\"nationalera region state\"))) OR (\"nationalere die stadte\"))*".
• Removing quotes may allow a broader search: (((( national regional state ) OR ( nationalera region state ))) OR ( nationalere die stadte ))*.
